China's aluminum industry is heading for a massive transition. China makes most of the world's aluminum, largely using coalfired electricity. The sector singlehandedly creates about 5% of China's carbon emissions. To meet the country's climate goals, producers will need to rebuild plants close to renewable energy sources. SP Global Ratings expects the transformation to be increasingly ...
